request transmission of the first screen displayed on the first display from the in-vehicle video display apparatus in real time, and

control the second display to display the first screen received according to the request in a region of the second display in real time.

5. The mobile terminal of claim 1 , wherein the controller is further configured to:

detect movement of the driver's eyes from the second display to the first display,

control the second display to stop displaying the first screen on the region of the second display, and

control the first display to display at least a portion of the second screen displayed on the second display on a region of the first display.

6. The mobile terminal of claim 1 , wherein the controller is further configured to detect movement of the driver's eyes from the first display to the display unit of the mobile terminal, and display on the display unit of the mobile terminal at least a portion of the first screen displayed on the first display, and

wherein the portion of the first screen displayed on the first display includes an image of a traffic light within the front visual field of the vehicle.

7. The mobile terminal of claim 1 , wherein the controller is further configured to:

subsequent to detection of the directional change of the driver's eyes from the first display to the second display, detect movement of the driver's eyes from the second display to a third display,

control the second display to stop displaying the portion of the first screen, and

control the third display to display the portion of the first screen overlapping with a third screen corresponding to a side visual field of the vehicle or a rear visual field of the vehicle, and

wherein the third screen is different than the second screen displayed on the second diplay.

8. The mobile terminal of claim 1 , wherein the controller is further configured to:

detect movement of the driver's eyes from the first display to the display unit of the mobile terminal, and

display on the display unit of the mobile terminal at least a portion of the first screen displayed on the first display.

9. The mobile terminal of claim 8 , wherein when an input applied to the first screen output on the display unit of the mobile terminal in a pre-set direction is sensed, the controller is further configured to change an output range of the first screen to correspond to the input.

10. The mobile terminal of claim 8 , wherein when an input applied to the first screen output on the display unit of the mobile terminal in a pre-set direction is sensed, the controller is further configured to display a screen displayed on a different display of the connected in-vehicle video display apparatus together with the first screen.

11. The mobile terminal of claim 8 , wherein when the driver's eyes to the display unit are not sensed for a pre-set period of time, the controller is further configured to:

stop displaying the first screen on the display unit of the mobile terminal, and

display an indicator icon for re-displaying the first screen to a region of the display unit of the mobile terminal.

12. The mobile terminal of claim 8 , wherein the controller is further configured to only display said at least the portion of the first screen to a region of the display unit when a vehicle running stop signal is received.

13. The mobile terminal of claim 12 , wherein the vehicle running stop signal corresponds to a stop operating state of a traffic light included in an image obtained by a front camera within the vehicle.

14. The mobile terminal of claim 13 , wherein when the stop operating state of the traffic light is changed to a go operating state, the controller is further configured to determine that a vehicle running resume signal has been input, and display a warning notification on the display unit of the mobile terminal.
